interference suppresor

[Jefftav]

Hi all,

I keep getting a lot of interference on my radio on MW channels which seems to get worse as I accelerate and dissappears when the engine is not running.

I have a suppresor to fit to the coil and assume it connects to earth via the body and the +side of the coil - Can anyone confirm this?

Any other ideas would be appreciated.

Cheers, Jeff

Jeff,

I found I needed to suppress my dynamo as well. That's what I was getting most of my noise from.

If you have the aerial fitted on the off side you have made it more
likely to suffer interference.

It depends whether you have pos or neg earth. The supressor needs to go between the side of the coil not connected to the points, and ground (the body). The points side has the condensor already, which is the same thing as your supressor. That of course assumes your supressor is a capacitor (round can with metal bracket, and 1 wire.

As well as the dynamo, check your plug leads. Are they suppressed leads? Supressed leads have a carbon conductor instead of copper. Sometimes you can have supressed pug caps instead of leads.
